Selenium is a brittle metalloid element with semiconductor properties, commonly available in elemental form for industrial applications. It is widely used in photovoltaic devices, photocopiers, and glass manufacturing due to its light-sensitive characteristics and ability to improve material properties. Engineers select selenium for its unique combination of electrical conductivity that varies with light exposure, making it essential in imaging technologies and renewable energy applications, while also serving as an additive in alloys and ceramics to enhance corrosion resistance and mechanical performance.
